T0 afl whom #may concern.'

Be it known that I, DONALD. l). STEVENS, a citizen of the United States, residing at St. Paul, in the Icounty of Ramsey and State of Minnesota, have invented a new and useful Smoking Pipe, of which the following is a specification.

My invention relates to smoking-pipes, and the object is to provide tobacco smokers with ar pipe that will -not easily clog and from which the creosote ofthe nicotine may readily be removed and needs only be removed at long intervals since an eXtra large surface is provided for holding it.

The accompanying drawing is a longitudinal vertical section of a smoking-'pipe embodying my improvements.

i lin said Adrawing 1i designates the bowl of the pipe and may be made of briar or any other suitable material, its tobacco space or bore 2 is preferably hemispheric in the bottom and is provided in its rear side with an aperture 3which is closed by the front side of a metallic thimble 4 having a small aperture 5 for thefsmoke to pass through from the tobacco, as indicated by the arrow 6. Said thimble is forced'into the bore 7 of the bowl where it may be. held by friction or other suitable means. The -thimblevis 'of so thin sheet metal that the aperture 5 does not form a duct of sufcient length for nicotine or its products to lodge therein.

Inserted and suitably held in the rear' part, 1a, of the bowl is the tubular stein 8 of the pipe, v the mouthpiece 9 having the smoke duct 10.

Detachably secured in the lower endof the mouthpiece is a tube 11 having its lower end 12 flared or funnel shaped. And s laced aboutsaid tube is a larger tube 13 which is also detachably secured to the mouthpiece but has its bottom end 14 closed and pref erabvly bowl shaped and spaced someA distance below the funnel 12. The upper end of the forward side ofthe tube 13 is provided with a smoke inlet aperture 15.

In the use of the pipe the smoke is-caused and in said stem is removably held.v

to pass as indicated by the arrows 6, 26a, 6 to the mouth piece and while the smoke is thus moving along, its nicotine is deposited upon the surfaces 16, 17, 18, 19 of the tubular parts of the pipe, but no nicotine can be drawn into the tube 11, because if any nicotineshould form liquid enough upon said tube to flow down alon its outer side, the

funnel 12 will prevent its entering into the l tube and will cause it to drip down and ac` lf the nicotine, 20 threatens to cover thek inner opening of the funnel 12 the pipe will make a'bubbling sound and thereby inform the user, who will'then take the pipe apart and clean out all the liquid nicotine and also wipe clean all the surfaces of the parts and assemble them again.

Y What I claim is:

ln a smokingl pipe,l the combination-of a bowl having a vertical bore for tobacco, a rearward bore for receiving a stein, a stem therein, a mouth piece detachably secured to the stein, and detachablysecured to the lower end of the mouthpiece and spaced within the stem a tube having its lower end closed and the upper end of its front side provided with a smoke aperture, a smaller tube spaced within the .-sald closed tube and having its upper end held in the mouthpiece and its lower end 'open and spaced from the -bottom of the closed tube, areduced bore within the bowl and opening into said rearward bore, the forward end of said reduced bore being semi-spherical and opening into the vertical bore of the bowl, and a thin metallic thimble fitted into the 4semi-spherical end of the reduced bore and closing the opening into the vertical bore of the bow1,`.and having an aperture inits upper side opening into the vertical hereI of the bowl In testimony whereof l affix my si nature.
